I have Adobe After Effects CS5.5 (v.10.5.1) and it keeps crashing when switching between AE and other programs. Here's a video so you can see what's happening.

I don't have any special plug-ins loaded except for what came with the program. OpenGL rendering is turned on and have tried turning it off to see if it make the problem go away and it doesn't make a difference.

Greatly appreciate any assistance I can get on this.

Computer System

Dell Precision M6600 Laptop

Intel(R) Core(TM) i7-2920XM CPU @ 2.50GHz

16GB RAM

2GB NVIDIA Quadro 4000M

Driver Version 285.62

Optimus is turned off so it's just the Quadro 4000M Card - no Intel HD Graphics in the background

No idea, but DynamicLink crashes always mean that it's losing connection to one of the relevant helper services, anything from qtserver32 to dynamiclinkserver itself. Since this happens when switching apps, it could mean that some security setting/ tool is isolating the programs and severing the link whenever they are sent into the background/ hibernation.... As a start, check your system event viewer what actualyl happens when the crashes occur. This might provide a clue....

Mylenium were right. I google the NtrigInterfacePressure.dll error and found out the driver for the touchscreen on my laptop was causing the crash. It's a known issue according to the manufacturer and they are working on an update for the driver.
